- Sorry about that Vi! I was trying to remember something off the top of
my head, and didn't have the issue to refer to.
Yesterday I neglected to mention that I use the ice bottle after making my
size (with room temperature water), BEFORE marbling. My studio gets hot
during the day, and I marble at night. When I pour the size in the tray, I
let it settle out for a bit. It doesn't take long to come up to
I had heard that carragheenan develops better viscosity below 65 degrees F.
A chemist at FMC corp. confirmed this. My ice bottle chills the size down
to 55-60 degrees, but slowly rises as the ice in the bottle melts. When I'm
ready to marble the next day, the size is cool, but not too cold, and after
letting it settle in the tray, the temperature isn't too cold at all. I
agree the colors and the size should be the same temperature.
I use the ice bottle to form a viscous size, rather than run my air
conditioning on full blast....
I'll also admit that I use the deionized water for conservation work, not
just marbling. I'm more concerned about the biological contaminants which
speed degradation rather than mineral.... It's very moldy here (spores
everywhere in the air) where the air doesn't move at all... A HEPA air
purifier also helps reduce these contaminants.
